Metal Clad Viton Seal, Press-In, Bag/5
Price: $27.18
Part Number: SX-77911-02

In vehicles with a 4L60 & E transmission, servo apply areas often need to be increased to improve 1-2 shift. This is often done by replacing the 2nd servo piston assembly, typically with the #553 version. This practice has caused an overabundance of used #554 servo assemblies and poor availability of quality #553 assemblies. Sonnax offers a 2nd Apply Servo Saver Sleeve, 77911-01, that salvages used #554 assemblies by allowing conversion of the #554 piston assembly into a #553 version. The sleeve is pressed into the existing #554 inner housing.

Features & Benefits

Sleeve is manufactured from high-quality aluminum for better wear resistance.
Metal-clad Viton?? seal restores hydraulic integrity at a worn 2nd apply servo piston.
2nd apply servo saver sleeve and piston bore seal converts used #554 assemblies with a minimal amount of machining, and provides the shift qualities of a new #553 assembly.
